w/filedownloader.filedownloader: tasks listener can't start, because can't find task provided listener, maybe tasks instance has been started in past, inusing, if in case, can use [basedownloadtask#reuse] reuse theme first start again: [ru.webant.projects.dossier.activity.mainactivity$7@18e962dd, true] onclick button "refresh":
public void refreshlist() { if (isonline()) { filedownloader.getimpl().pauseall(); final restserviceapi apiservice = servicegenerator.createservice(restserviceapi.class, getstring(r.string.base_url), remindtoken()); getcontent(apiservice); } else { toast.maketext(mainactivity.this, getstring(r.string.no_internet_connection), toast.length_short).show(); } } getcontent(apiservice) gets list of files , calls method:
